Hi,

The University of Southampton is connected to m6bone/GĂ©ant via a tunnel. I am able to asmping and ssmping Stig's ssmping server in Norway ok. I am unsure of the details of how m6bone is connected to Internet 2?


Using asmping to test multicast connectivity to Norway (using our own embedded-RP):
asmping -6 ff7e:140:2001:630:d0:f000:4321:1234 ssmping.uninett.no

Using ssmping to test SSM connectivity to Norway:
ssmping -6 ssmping.uninett.no


We have an ssmping server on our network, are you able to ping it?
ssmping -6 ssmping.ecs.soton.ac.uk
asmping -6 ff7e:140:2001:630:d0:f000:4321:1234 ssmping.ecs.soton.ac.uk


Anyone else had any success from Internet2?

I see that I did get one multicast packet. Also I see that state was built for the asmping group ff7e:140:2001:630:d0:f000:4321:1234.

But state was not built for ff7e:140:2001:630:d0:f000:8000:1217.

I've tried to connect to ff7e:140:2001:630:d0:f000:8000:1217 but it doesn't work.

I have successfully viewed an IPv6 stream from the Vatican which also used enbedded RP.

Apologies for cross-posting.


I have made three more of the Virgin Radio satellite streams available on IPv4 and IPv6 multicast:

- Virgin Radio Groove
- Virgin Radio Classic Rock
- Virgin Radio Xtreme

More information is available at:
http://www.multicast.org.uk/virginradio/

They are all MPEG-1 Audio Layer-2 streams (payload 14) over RTP on port 5004.


Virgin Radio have also made some Windows Media Player multicast streams available themselves:

Thanks,
